Question about Texas Instruments TI-89 Calculator
Less than a week ago I found that one of the batteries leaked and it had all gunk in the battery compartment. I cleaned it, then replaced the batteries. Once I put the batteries in, the TI turned on but it when i press any buttons, it doesn't respond. I tried resetting it, but it still doesn't work. How can I get this thing to work?
I don't know how you went about cleaning the battery contacts but if there was any chance to have gotten moisture into the case, it may never work again.
The circuits operate with currents in the nano & femtoampere range and even a breath of moisture can temporarily disable them because of stray currents.
The failed battery may have also damaged fine printed circuit traces as well.
